Rajendra Pachauri, head of the UN's Intergovernmental Panel on Climate Change (IPCC)

We all knew it was coming...

Back in 2006, this column reported on the UN's conclusion that livestock farming created more greenhouse gas emissions than all planes, trucks, and automobiles combined. Predictably, the UN is now asking that we "shun meat" to fight climate change. While various lawmakers have proposed banning everything from plasmaTVs to sports cars, this call came from a substantially higher level.

Rajendra Pachauri, the Indian economist who chairs the UN IPCC, has proposed the changes. Pachauri, who is himself a vegetarian, believes the only solution to prevent global catastrophe is for us to cut down on our burgers, steaks, and BBQ chicken.

Despite his lack of any formal credentials in climatology or physical science, Pachauri has just been reelected to his second six-year term at the head of the world's most powerful climate organization.

The UN Food and Agricultural Organization estimates 18% of human-generated greenhouse gas emissions come from meat production. By contrast, only 13% of emissions come from transport.

Pachauri's remarks were made at a Compassion in World Farming Meeting in London yesterday, a group which believes killing animals for food is morally wrong. CIWF Spokesperson Joyce D'Silva, who attended alongside Pachauri, enthused over the possibilities of reducing meat consumption, "The climate change angle could be quite persuasive.”

"Surveys show people are anxious about their personal carbon footprints and cutting back on car journeys and so on; but they may not realize that changing what's on their plate could have an even bigger effect", she said.

D'Silva called for a Kyoto-like International Treaty to regulate meat production and consumption. Pachauri himself favors a more indirect approach, the so-called "carbon tax" he has advocated on previous occasions:

If there were a (global) price on carbon perhaps the price of meat would go up and people would eat less. But if we're honest, less meat is also good for the health, and would also at the same time reduce emissions of greenhouse gases.

In related news, an Australian researcher has proposed that we return to hand-washing of clothes to combat climate change. Hand washing clothes would be much friendlier to the environment, the study concludes

Even more exciting is his discovery that "smell-friendly" cotton can be worn without washing more times than a polyester blend, further reducing our energy consumption:

Mr. Navarro, who was commissioned to do a "cradle-to-grave" study of the energy costs of clothing manufacturers, said the use of "smell-friendly" fibers would assist in increasing the number of times a shirt is worn between washes.

"Research shows that polyester is related to more intense sweat odor than cotton," he said.

"This means it is easier to wear a cotton t-shirt more than once before washing than a polyester t-shirt.

Critics of the environmentalist movement have often claimed they're "trying to turn us all into stinky, unwashed vegetarians". With these technology advances in "smell friendly fibers", it's a relief to see at least we don't have to worry about the stink.
